Werewolf By Night first appeared in Marvel Spotlight #2 (Feb. 1972) although who created what aspects of the character comes down to something like the premise being based on an idea by Roy Thomas, while the series name was suggested by Stan Lee, and yet the debut story was created by Gerry Conway and Mike Ploog. The characters self-titled series began in September 1972 (lasting for 43 issues which ran through March 1977). Issue #32 features the first appearance of Moon Knight. Jack Russell (aka the Werewolf) briefly co-starred with “Tigra” in Giant Size Creatures #1 (July 1974), which first featured the transition of Greer Grant into the new role of Tigra (instead of her original identity as simply The Cat). The series was retitled Giant-Size Werewolf with its second issue.As the Werewolf By Night, Jacob Russoff (his given name) obviously had the ability to transform into a werewolf, which gave him superhuman strength, speed, stamina, agility, durability, reflexes and a heightened sense of smell; plus an accelerated healing factor and razor sharp claws and teeth.
